Your symptoms?jaw stiffness and pain above the ears?suggest tension headaches or migraines, which can be triggered by specific foods. Cold items like ice cream and lassi can cause sudden blood vessel changes, while chocolate and fermented dairy like buttermilk contain compounds that trigger headaches in some individuals. This tension often starts in the jaw muscles and spreads upward. Disprin, which contains aspirin, helps by reducing pain and inflammation. I highly recommend keeping a food diary to track these triggers and sharing this with a doctor to find a personalized, long-term solution.
